AMR and zoonotic diseases

Antimicrobial resistance (AMR) represents a critical global health challenge that intersects with the One Health approach, emphasizing the interconnectedness of human, animal, and environmental health. AMR develops when microorganisms, including bacteria, viruses, fungi, and parasites, evolve resistance to the drugs designed to kill them. This resistance can arise from the misuse and overuse of antimicrobials in human medicine, veterinary practices, and agriculture, where drugs are used to treat infections or promote growth. The One Health framework is essential for addressing AMR as it recognizes that resistance can spread across these domains, impacting both human and animal health and contaminating the environment.

Zoonotic diseases, which are infections transmitted from animals to humans, further illustrate the importance of a One Health approach in tackling AMR. Many zoonotic diseases are managed using antimicrobials in veterinary medicine, and resistance in these pathogens can directly affect human health. For example, the misuse of antibiotics in livestock can lead to the emergence of resistant bacteria that can spread to humans through direct contact, food, or environmental pathways. Therefore, a holistic strategy that integrates human health, animal health, and environmental protection is crucial for controlling AMR and preventing the spread of zoonotic diseases, ensuring a coordinated and effective response to this global health threat.
